Enables the V4L2 sub-device pad-level userspace API used to configure
video format, size and frame rate between hardware blocks.
This API is mostly used by camera interfaces in embedded platforms.

Say Y here to enable the old-style fixed-range minor assignments.
Only useful if you rely on the old behavior and use mknod instead of udev.
When in doubt, say N.
